Revised proposal feedback:
Ok. Go ahead to plan details of the investigation experiment(s). Remember to control variables like container, volume of liquid, temperature of environment etc.

Feedback on draft proposal:
1. You would need to find a "safe" place, and place a sign e.g. "Science Expt in progress, do not touch" etc.to ensure the liquids are not touched.
2. The location should also not have direct sunlight at certain times of day.
3. Time and temperature of the location should be monitored and recorded regularly where possible.
4. Need not use 12 hours, a smaller volume of liquid would require shorter time. Test it out with different amount of a liquid.
5. It would even be better if experiments carried out by each member at different locations with different environmental conditions.
Think about the suggestions, update proposal and carry out your experiments soon Good luck!
